Ledyard Transmission Tie-In, Ledyard, IA

April to June 2022. 

This was an 1,850’ 345kV transmission line to connect the Ledyard Substation to an existing switchyard. The line consisted of two self-supporting steel structures (155’ & 165’ tall) on concrete piers (10’ dia. x 42’ deep & 10’ dia. x 46’ deep) and one 135’ direct buried steel structure. The extreme high of the structures was due in part to the fact that the line crossed over and existing 161kV transmission line.
